This introduces a patch to our GCC (10.3.0) mingw-w64 compiler, in Guix, to make it avoid using aligned vmov instructions. This works around a longstanding issue in GCC, https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54412, which was recently discovered to be causing issues, see #24726. Note that distros like Debian are also patching around this issue, and that is where this patch comes from. This would also explain why we haven't run into this problem earlier, in development builds. See: https://salsa.debian.org/mingw-w64-team/gcc-mingw-w64/-/blob/master/debian/patches/vmov-alignment.patch. Fixes #24726. Alternative to #24727.
